STOPPINGDEVICEIFOR Looms.

srnorrrcnrron aimin part of Letters Patent No. 707,130, dated August 19, 1902.

Application filed April 21, 1902.

the following to be a full, clear, and exact description of the invention, such as -will en-. able others skilled in the art to which it ap-' pertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this'specification.

This invention relates to'looms, and particularly to narrow-ware looms; and it has for its object to provide an improved construction of mechanism for stopping the operation of a loom whenever a stoppage or ill-timed movement occursjn the action of the rackbar with reference to the action of other parts of the loom.

The invention consists in an improved stop mechanism for looms constructed substantially as will be hereinafter described and finallyembodiedin the-clauses of the claim.-

In the accompanying drawi ngs,Figure 1 isa top plan view .of my invention, showing enough of the loom to properly illustrate the invention; and Fig. 2 is a side view of what is seen in Fig; 1. e

In said drawings, ais a portion of one side frame of the loom; b, the breast-beam; o, the batten carried by lay-swords d; e, the reciprocating rack-bar, ,andf one of the shuttleblocks.

On the side frame a is secured, as by bolts g, a substantially L-shaped arm h, carrying a pair of slotted brackets t, which support and in whose slots j is guided, by means of pins 70, a blockZ. q The pins is are carried by and project downwardly from the block Z, their guiding action being augmented by bolts m, which'are carried by the arm h and penetrate the block Z in such manner that said block is free to slide thereon. The block Z carries a'push-rodor throw-offipin n, which projects toward and into an opening 0 in the arm h.

p is an adjustable arm made in two parts, having a slot-and-pin connection q between Serial No. 103,842. (No model.)

them, whereby theadjustment of said arm is efiected. This arm is carried bythe'rackbar 6 and has its front end hook-shaped, as at 7". By virtue of the combined actions of the rack-bar and batten this arm normally takes an arc-shaped movement, which causes its hook-shaped portion 1' to pass out and around the block 'Z without engaging it. Should the rack-bar stop moving, however, or should its motion become ill-timed with reference to the action of the batten, said hook I", will be caused to, pull on said block Z, and thus thrust the push-rod inwardly.

sis a plug which fits'in'the opening 0. By means of a chain it, passing around pulleys u, suitably arranged in stationary parts of-the loom, this plug is connected with a rod '0, which is adapted to impinge against a' lug 'w on the hand-rail 00 of the loom, to which the belt-shipper y is connected in the usual manner. When the plug 3 is in its'opening 0,-it acts through the chain t to'holdrodoout of engagement with the' lug'w, acting against a spiral spring ,2, which is coiled between one end of a casing 1 and a shoulder 2 on'said rod, said casing being secured to the breast-beam and receiving the coiled spring and serving as a support for the rod.

It being remarked that plug sis normally disposed in the opening 0, thus holding rod 12 out of contact with lug w, and that the inward thrust of the-rod n will be sufficient to displace the plug from the opening, so as to release rod o, it is believed that in view of the above-described coaction between parts 19 and Zupon any irregularity in the action of the rack the operation of the mechanism will be fully understood.

Having thus fully described" my invention,

what I claim as new, and desire to secure by trolled by said reciprocating part, for forcing said plug from the opening, substantially as prising coactive members carried the one by described. said reciprocating part and the other by said 15 2.
